Whack!
There were hilarious scenes as two young bear cubs were pictured play-fighting.
Affectionate kiss-like nuzzling soon gave way to a paw-punch to the face for one unlucky youngster.
But the two remained friends and calmed down for a stroll and to hang out with their long-suffering mother.
The bears were photographed by Ahmed Abu Ganem in Kamchatka, Russia.
